On a project, we are utilizing the IR-AQ04-VI card with all 4 outputs being set to ±5Vdc. When the first output is activated, we can measure the voltage out at 0.38Vdc (Good baseline).
When the 2nd output is activated along with the 1st still on however, both output drops to 0.25Vdc.
When the 3rd output is activated, along with the 1st and 2nd, all three output drops to 0.12Vdc.
We have confirmed that the power supply is still holding at 24Vdc feeding the full system when these motors are turning on. Is there something with the settings of the card to keep the channels isolated?
Can re-confirm when machine powers on, but Analog Output #0: 3200
That is correct. The motor drive was wired direct to the analog output card. Could watch the first motor slow down as additional motors were turning on.
